Subjective magnitude of auditory impairment. A pilot study

A study of two samples (one in London, the other in Cairo) of patients who were suffering from an impairment of hearing showed that the subjective magnitude of auditory handicap was significantly correlated to the average hearing level at 2 000 Hz for the two ears. For both samples, the subjective magnitude of the auditory handicap was shown to be a power function of the hearing loss expressed in terms of the sound pressure corresponding to the threshold of hearing. The exponents in the power function applying to the two samples were similar. Age, sex and pain threshold did not influence the estimation of the subjective magnitude of auditory handicap in this study.
